Soaking it Up = Infiltration

Infiltration happens when water soaks into the soil from the ground level. It moves underground and moves between the soil and rocks. Some of the water will be soaked up by roots to help plants grow. The plant s leaves eventually release the water into the air through the plant s pores.

Some of the water keeps moving down into the soil to a level that is filled with water, called ground water. The very top of this layer filled with ground water is called the water table.
